WILLIAM D. KELLY, OF CHICAGO, ILLINOIS, ASSIGNOR TO BUR-KEL MANUFACTURING. GOMPANY,OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

To all whom it may concern Be it known that I, lVILLIAM D. KELLY;

a citizen of the United States, residing, at Chicago, in the county of Cook and :State of Illinois, have invented certain newanduseful Improvements in Gluing-Machines, of'

, plythe glue to the surface to be joined.

Glue plates of various types have been employed prior to my present invention and,

while they are capable of applying glue to a 3 smooth surface in a very satisfactory man ner, they are notsuitable forapplying glue to tongues and grooves, mortises and tenons,

V or articleshaving rough and irregular sur faces which it 1501 17611 desirable n thewoool-l working'art to join together.

My present invention has for one of its primary objects the provision of a glue plate which will be adapted to apply glue in a satisfactory manner to either flat or rough and irregular surfaces.

Another object of the invention isto provide a glue plate which will normally present a fiat glue-carrying surface, which surface, however, shall be so constructed that its various component parts willbe adapted to yield under pressureof the article tobe glued, so that the surface willconform to and substantially assumethe general shape;

of the surface presented to it for the reception of the glue. a v

A further object is. to provide a machine with a work support adapted to hold' the work or articles to. be glued in position above the glue plate and in the path of the travel'thereof to receive a supply of glue 1 7 when the plate is elevated into contact there- With.

For. the purpose of facilitating the explanation. ofmy invention, I have shown on the accompanying drawings a gluing ma chine of conventional form equipped-with a preferred andv practical embodiment ofrny invention from which, when considered in conjunction with the following'description,

the principle of my invention will be readily understood.

' On the drawings reference character 6 indicates a standard or table supporting a water tank 7 which may be heated in any suitable manner, a steam coil 8 being shown in the present instance as illustrative of one mode of heating the same. The water tank carries two or more upwardly extending studs or pins 9 which serve as guides for a frame or rack 11 upon Whichthe glue plate is mounted. The glue pot 12 is arranged withinthe Water tank so that the rack or frame 11 with the glue pot thereon may be immersed in the'hotglue in the glue pot. A rock-shaft 10 is mounted in the frame 6, and provided at itsends with arms 13 which,

in turn, are connected to the ends of the rack 11 by links 14, whereby upon oscillation of the shaft 10 the rack and glue plate are submerged in the hot glue and lifted out'into the position shown in Fig. 1, so that the glue carried by the plate may be applied to the article to be glued. A pedal 15 is pivotally mounted, preferably on a cross-shaft'16, near the floor, in position to be operated by the 1 foot and is connected by a link 17 with an arni 18 fixed on the rock-shaft 10. A spring 19 and suitable counter-weights 21 may be employed, if desired, tofacilitate the raising and lowering of the glue plate. The mecha nism thus far described may be of any well known or preferred construction, but pref erably designed so that the rack 11 withthe glue plate thereon will be normally submerged in the hot glue.

My novel glue plate, designated generally by reference character 22, is adapted to rest uponand be carried by the rack 11. bince it is often desirable to apply glue to the edges of stock or to tongues or grooves, I

have so designed and constructed my glueplate. that .it is'capable of conforming in a general way to the shape of the article against which it is pressed, thereby carrying the glue into the depressions or'grooves of thevarticle with the result thata uniform.

formed by making the individual elements out of resilient wire of any preferred crosssectlonal shape, each being bent to provide ashank 25 extending at an angle from the base 23,'a topv portion 26 disposed in a substantially horizontal plane, and a de-v pending end 27, all as shown in Fig. 2. The glue-carrying elements are preferably mounted on the base 23 so that their tops or glue-carrying portions 26 are arranged in staggered relation and all lie in a common andsubstantially horizontal plane when the plate is mounted on the supporting'rack 11.

The ends 27 are turned downwardly, as

shown, to maintain the relative positions ofthe elements and prevent them from lapping over each other, particularly when one or more of them is depressed relatively to the other. Since the material from which the glue-carrying elements are formed is resilient in character, it will be obvious that the shank will yield sufliciently'to permit the depression of one or more of the elements relatively to the others when pressure is applied to its upper surface or glue-carrying portion 26. This construction, therefore, affords a yielding surface which is adapted to conform automatically to any irregularities in the surface of the article to be glued.

, I have shown, for instance, in Figs. l and 5, apiece of stock 28 as disposed upon the upper surface of the glue plate, this stock being shown as provided on its lower face with tongues 29 and grooves 31. From Fig. 5 it will be observed that when the plate is pressed against this piece of stock the gluecarrying elements beneath the tongues will be depressed while the intermediateelements will enter, the grooves 31,

thereby applying glue to the bottoms of the groves as well as to theouter faces and sides of the tongues. It will be understood, of

course, that the tongue and groove formation is shown merely for purposes of illustration;

and that thesurface of the plate is capable of conforming to any irregularities in the surface-of the article or stock to be glued.

--For the purpose of supporting the work in position to receive the glue from .the plate as the plate is moved into operative relation therewith, I have provided a plurality of supports which are shown as carried by the glue pot 12 at the endsof theplate. The stock is 1am upon these supports and then by means of the treadle and operating Q mechanism actuatedthereby the plate is elevatedlinto engagement with the stock- 150 deposit t q ntity ofglue .upon the lower face of the stock. x

"rile plate which l' have illustrated is Fig.

l is made up of two sections, but, it will be obvious, that the plate might be made in any desired number of sections and'thework support likewise might be of any fother preferred construction. It will be understood, of course, that the rack 11 is merely a frame for s'upportingthe glue plate which permits the glue to drain back into the glue pot when the frame and'platje are raised. Normally, the plate is immersed in the hot glue but, when itis desired to apply glue] I to an article, the plate is elevated into the position shown in Fig. lby the mechanism previously described, whereupon the surface of the stock engaged thereby receivesa supply of the glue. Thesurplus glue runs back into the glue pot as the plate is raised. If a smooth or'flat' piece'of stock is to be glued the glue-carrying elements will be depressed but slightly and all an equal amount,

but, if thestock is oftongue and 'groove formatlon, or hasany' irregular surface, the

glue-carrying elements will be depressed individually proportionately to the pressure exerted upon them.

In the form-of my invention illustrated in Figs 6, 7 and 8 the glue platedesignated generally by reference character'BZ com prises a series of glue-carrying elements 33 in the form of narrow bars or plates arranged in parallel relation upon the rack 11. 'These' bars or plates may be of 'any preferred width and are preferably provided with apertures 34 through which the glue may drain'back into the glue pot whenthe plate is raised. Each element is designed to yield independently of the others under the influence of pressure exerted upon its upper face and, for the purpose of yieldinglysupfporting the elements with their upper faces normally ma substantially horizontal'plane, I have provided coiled expansion springs 35disposed beneath and preferably adjacent the ends of each element, whereby the ele' ments are yieldingly supported upon the rack 11. For the purpose of preventing displacement of the elements and of guiding pair of links 36 pivotally connected at one.

end to the rack 11 by socket and pin connections 37, the other ends of the links being slidably and pivotally connected to an ele-' ment 33 by slot and pin connections 38. Since the links 36 of each pair are oppositely disposed, it will be manifest that the gluecarrying elements will be restrained by the links to a substantially right line up and down movement. The elements, therefore, are each yieldingly and independently supported and guided so that each of them may yield independently of the others when pressure is applied to its upper surface. In practice the width ofthe individual elements will usually be determined by the character and shape of the work to be glued by the machine.

In Figs. 9, 10 and 11 I have illustrated an other form of glue plate designated generally by reference character 39, this plate being also made up of a series of individual glue-carrying elements, one of which is shown in perspective in Fig. 10. These elements, as will be obvious from this figure, comprise a bar or plate 11 provided with a series of elevations or glue-carrying projections 42, the bars between the individual projections being preferably provided with perforations lS'through which the glue may drain back into the glue pot as the plate is raised. For some kinds of work this form of plate is preferable to that shown in Figs. 1 to 5, or that shown in Figs. 6 to 8, but, it will be understood that my invention does not reside in the specific construction of the glue-carrying elements, since the structure of these elements may be varied to suit the requirements of the work to be glued.

While the elements 11 of the plate 39 may, if desired, be mounted in the manner shown in Fig. 6,I have shown in Fig. 11 another manner of mounting the elements which, in some instances, may be preferable. The glue-carrying elements 41 as shown in this figure areconnect-ed to the rack 11 by means of links 14 pivotally connected at 45 to the rack and at e6 to an element 41. The links in this instance are both disposed in the same direction so that a reciprocatory movement is imparted to the glue-carrying element when pressure is exerted upon its upper surface. The elements are each normally retained substantially in the position shown by means of contraction springs 47 attached at one end to an end of the rack 11 and at the other end to an element 41. The elements are, therefore, yieldingly supported to normally present a substantially flat glue presenting surface, but, each of the elements is adapted to yield independently of the others, upon application of pressure to its upper face. while the glue-carrying plates 32 and 39, illustrated in Figs, 6 to 11, inclusive, are shown as consisting of glue-carrying elements, the lengths of which are substantially equal to the length of the plate, it will be manifest that the elements may be of any desired length, a number of them being disposed in longitudinal alinement to make up a plate of the requisite length. each element, of course, being independently mounted to yield independently of the others.

It is believed that my invention will be fully understood from the foregoing and, since many modifications in the details of construction shown and described will suggest themselves to those skilled in the art, it will be obvious that the invention is not restricted to the structural details disclosed but is capable of variations within considerable limits withoutexceeding the scope of the following claims:

I claim:

1. A glue plate for a gluing machine, comprising a plurality of glue-carrying elements, each having an inclined shank, a substantially horizontal top and a downturned end, said elements being arranged in staggered relation.

2. In a gluing machine, the combination of a glue pot, a vertically reciprocable frame, and a glue plate carried by said frame comprising a plurality of glue-carrying elements, each having an inclined shank, a substantially horizontal top, and a down-turned end.

3. In a gluing machine, the combination of a glue pot, a vertically reciprocable frame, a glue plate carried by said frame comprising a plurality of glue-carrying elements, each having an inclined shank, a substantially horizontal top, and a down-turned end, and means for reciprocating said frame to move it into and out of said glue pot.

4. A glue plate for a gluing machine comprising a vertically reciprocable frame, a plurality of glue-carrying elements mounted thereon and arranged in parallel relation, each of said elements having 'an inclined shank secured to said frame, a substantially horizontal top, and a down-turned end.
